THERMOSETTING BAMBOO SAND COMPOSITE PRESSURE PIPE
FIELD OF THE INVENTION
[0001] The invention relates to a thermosetting bamboo-sand composite pressure pipe, which is suitable for use in the technical fields of agricultural irrigation, water supply and drainage, and petrochemical anticorrosion.
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
[0001] The invention relates to a thermosetting bamboo-sand composite pressure pipe, which is suitable for use in the technical fields of agricultural irrigation, water supply and drainage, and petrochemical anticorrosion.
BACKGROUND OF THE INVENTION
[0002] In current agricultural irrigation, water supply and drainage, and petrochemical anticorrosion industries, traditional pipes, such as cement pipes, polyvinyl chloride pipes, polyethylene pipes, polypropylene pipes, FRPpipes (glass fiber reinforced plastics pipes, glass fiber reinforced plastics mortar (FRPM) pipes), steel pipes, and ductile iron pipes are generally used. Cement pipes have low production cost but low strength, heavy weight, and leaky pipe joints. Polyvinyl chloride pipes, polyethylene pipes, polypropylene pipesare lightweight, smooth, and corrosion resistant but insufficient in rigidity and strength, and the raw materials thereof are all synthetic petrochemicals. FRP
pipes and FRPM pipes have strong corrosion resistance, high strength, small fluid resistance, and large rigidity, but the raw materials of thereinforcedmaterials in the products is glass fiber with high energy consumption. While the resin is petrochemical and the products and wastes thereof are non-recyclable andpollutional. Metal pipes, such as steel pipes and ductile iron pipes, have high strength but poor corrosion resistance, high energy consumption, and high pollution. Therefore, the use of such traditional pipes not only consumes a large quantity of petroleum and mineral resources, but also results in high energy consumption, high emission, and large depletion of non-renewable resources.

[0003] Chinese Patent Application No. 2009201212098 entitled "bamboo fiber winding , CA 02927542 2016-04-14 composite pipe" discloses a structure including an inner liner layer, a reinforcement layer, and an outer protection layer arranged from the inside out in the radial direction. The reinforcement layer is a bamboo fiber layer formed by winding continuous bamboo fiber strips on the inner liner layer. The bamboo fiber layer is acircular layer of the bamboo fiber strips, a spiral layer of the bamboo fiber strips, or a combination thereof. And at least twobamboo fiber layers are designed. This bamboo composite pipe satisfies advanced concepts of energy saving and renewable resources, and the price thereof is much cheaper than the traditional pipes (except the cement pipes). However, in some application fields with low pressure and high rigidity, especially for agricultural irrigation, the price of this bamboo composite pipe is still high.
SUMMARY OF THE INVENTION
SUMMARY OF THE INVENTION
[0004] In view of the above-described problems, it is one objective of the invention to provide a thermosetting bamboo-sand composite pressure pipe that is energy saving and environment protective and has renewable raw materials and cheap price.
[0005] Technical scheme of the invention is as follows:
[0006] A thermosetting bamboo-sand composite pressure pipe comprises: an inner liner layer, an inner reinforcement layer, a sand-adhesive thickening layer, an outer reinforcement layer, and an outer protection layer. The inner reinforcement layer formed by winding bamboo strips, the sand-adhesive thickening layer formed by mixed ore sand and adhesive, and the outer reinforcement layer formed by winding bamboo strips are respectively disposed between the inner liner layer and the outer protection layer from the inside out. The invention adopts multi-layer composite structure, the inner reinforcement layer and the outer reinforcement layer adopts environmentally friendly and renewable bamboo. As a regenerative and environment protective resource, the bamboo possesses lightweight, high strength, anticorrosion, cheap price, and wide distribution.
The sand-adhesive thickening layer not only increases the rigidity of the pipe, but also reduces the usage of the bamboo, thus further decreasing the production cost.
The sand-adhesive thickening layer not only increases the rigidity of the pipe, but also reduces the usage of the bamboo, thus further decreasing the production cost.
[0007] The bamboo strips of the inner reinforcement layer are regularly wound and adhered to an outer surface of the inner liner layer. The sand-adhesive thickening layer comprises a mixture of ore sand and adhesive uniformly coated on an outer surface of the inner reinforcement layer. The bamboo strips of the outer reinforcement layer are regularly wound and adhered to an outer surface of the sand-adhesive thickening layer.
When winding the bamboo strips of the inner reinforcement layer and the outer reinforcement layer, a certain amount of an amino resin is simultaneously added, and the thickness of each layer is in accordance with the use requirement to enable the pipe to reach a designed strength. In the sand-adhesive thickening layer, an ore sand having high hardness and low price is employed. The ore sand and the resin adhesive are evenly mixed and coated on the outer surface of the inner reinforcement layer, and the thickness of the sand-adhesive thickening layer is designed according to different use requirement.

In the sand-adhesive thickening layer, an ore sand having high hardness and low price is employed. The ore sand and the resin adhesive are evenly mixed and coated on the outer surface of the inner reinforcement layer, and the thickness of the sand-adhesive thickening layer is designed according to different use requirement.
[0008] The bamboo strips of the inner reinforcement layer and the outer reinforcement layer have a length of between 0.5 and 2 m, a width of between 5 and 10 mm, and a thickness of between 0.3 and 1 mm. The bamboo strips of such size have low processing difficulty, high utilization, reduced production cost, and sufficient adhering strength in thermal expansion and cold contraction conditions.
[0009] In the inner reinforcement layer, the bamboo strips are first radially wound to form a first radial layer to adhere to the outer surface of the inner liner layer. The bamboo strips are then axially wound to form a first axial layer to adhere to an outer surface of the first radial layer. The winding of the bamboo strips in the radial direction and subsequent in the axial direction is able to optimize the loading performance of the pipe.
[0010] In the outer reinforcement layer, the bamboo strips are first axially wound to form a second axial layer to adhere to the outer surface of the sand-adhesive thickening layer.
, CA 02927542 2016-04-14 The bamboo strips are then radially wound to form a second radial layer to adhere to an outer surface of the second axial layer. The outer reinforcement layer is wounded by the bamboo strips in the axial direction and then in the radial direction, the order of which is opposite to the winding of the inner reinforcement layer, thus the loading performance of the pipe is further optimized, and the appearance of the pipe is much better.

[0011] In the outer reinforcement layer, the bamboo strips are radially wound to form a second radial layer to adhere to the outer surface of the sand-adhesive thickening layer.
The outer reinforcement layer can also be wound by the bamboo strips in the single radial direction according to different use requirement so as to reduce the production cost to the utmost on the basis of ensuring the use strength of the pipe.
The outer reinforcement layer can also be wound by the bamboo strips in the single radial direction according to different use requirement so as to reduce the production cost to the utmost on the basis of ensuring the use strength of the pipe.
[0012] The inner liner layer is formed by adhering a bamboo fiber nonwoven fabric to a needled bamboo mat by anadhesive, and a thickness of the inner liner layer is between 1.2 mm and 2.5 mm. The inner liner layer of the above material and thickness features anti-seepage, anticorrosion, sanitation, and smooth inner wall. In addition to the above nonwoven fabric and the needled mat, other types of nonwoven fabric and needled mat can be adopted according to different transmission media.
[0013] The outer protection layer is coated on an outer surface of the outer reinforcement layer, and a thickness of the outer protection layer is between 0.5 and 1.5 mm. The outer protection layer adopts anticorrosive and waterproof materials. When the pressure pipe is used in good external environment, the thickness of the outer protection layer can be much thinner, and a minimum thickness of 0.2 mm is able to satisfy the protection function.
[0014] The inner liner layer, the inner reinforcement layer, the sand-adhesive thickening layer, and the outer reinforcement layer are adhered and cured integratedly.
Thus, the product reaches the designed strength and rigidity, which is convenient for package, storage, and transportation.
